This program is a little utility to convert 3D files to a number of
other 3D formats. It can generate smooth triangles for those formats
that support it, allowing you to specify the angle under which the
faces should be smoothed.
INPUT
This version supports the following input formats:
- .RAW
Simple RAW format in the form: pnt0 pnt1 pnt2
Multiple objects are supported if the file is in the form:
NAME_OBJECT1
pnta00 pnta01 pnta02
pnta10 pnta11 pnta12
pnta20 pnta21 pnta22
...
NAME_OBJECT2
pntb00 pntb01 pntb02
pntb10 pntb11 pntb12
pntb20 pntb21 pntb22
...
see chess.raw for an example.
- .3DS
Binary mesh format for 3D Studio (Trademark ...)
only objects with faces are supported
Highlight output does not work (convert to RAW first and then to OBT).
- .OBJ
Binary mesh format for Imagine 2.x/3.x (Trademark ...)
only objects with faces are supported
Tip: If you have a object generated in the form - editor, load it
into the detail editor, select it, use the "merge" command and
save it as a ".obj" file. Now the object is ready for converting.
Tip: If you have object files with the extension .iob (Amiga
extension ??) rename it to ".obj".
Highlight output does not work (convert first to RAW and then to OBT).
OUTPUT
This version supports the following output formats:
- .RAW
The converter can generate a smooth RAW from an unsmoothed
RAW and vice versa.
- .UDO/.INC
Userdefined Object format for Moray V2.x and a inc file for
POVRAY or POLYRAY.
The converter writes a UDO file and a corresponding POV-Ray or
Polyray include file, generating triangles (poly's) and
smooth_triangles (patches). Use the /e parameter to reduce
the edge count if you are getting too many edges in the UDO file.
A value of /e5 will retain just about all edges that are not coplanar.
A value of /e60 will throw out lots of edges and retain only pretty
sharp contours.
- .ASC
ASCII object format for 3D Studio
- .OBT
ASCII object format for Highlight Pro
Converts only RAW to OBT
- .RPL
ASCII object macro format for Real 3D. (Version 3.12)
- .3DS
Binary object format for 3D Studio
If inputtype and outputtype are the same, $$$ is used as filename.
Usage:
3dto3d xxxx [options]
Example:
raw2_3d chess /e20 /t3
Options:
/svalue (value = Smoothing Angle in degrees, default 70.0°)
- smoothes tri's with a normal angle below value
affects only output of /o1, /o2, /o3
/evalue (value = Edge Detect Angle in degree, default 0.0°)
- throws out edges with an angle below value
affects only the UDO file created with /o2 and /o3
/v(Verbose on)
- gives status messages on the progress of the conversion
/tvalue (value = Swapmode)
value = 0 normal (default);
value = 1 swap X <-> Y;
value = 2 swap X <-> Z
value = 3 swap Y <-> Z
- swaps axis
/ivalue (value = Inputtype)
value = 0 RAW (default)
value = 1 3DS (3D Studio)
value = 2 OBJ (Imagine)
/ovalue (value = Outputtype)
value = 0 RAW
- makes a pure RAW file for testing
form: pnt0 pnt1 pnt2
val = 1 Smoothed RAW
- makes a smoothed Raw file
form: pnt0 norm0 pnt1 norm1 pnt2 norm2
val = 2 UDO + POV/INC <Moray/Povray>(default)
- makes a POVRAY include File with triangles
and a MORAY UDO file
val = 3 UDO + POLY/INC <Moray/Polyray>
- makes a POLYRAY include File with triangles
and a MORAY UDO file
val = 4 ASC <3DStudio>
- makes a 3DStudio ASC file
val = 5 OBT <HighLight>
- makes a HighLightPro OBT file
(only works with RAW files)
val = 6 RPL <Real3D Macro>
- makes Real3D RPL file, ASCII Macro
val = 7 3DS <3DStudio>
- makes a 3DStudio binary file
val = 8 UDO + POV/INC <Moray/Povray>(wire)
- makes a POVRAY include File
and a MORAY UDO file
For every edge in the object a cylinder
and for every vertex a sphere is outputted
The radius is controlled via /s
/s1.0 for radius 1.0
The goal is to make a real wireframe object
Try it !!!
